Abstract: Systems and method for providing functional magnetic resonance imaging (fMRI) data analysis and comparison services are provided. The system comprises an interface, a processing engine, an fMRI comparison engine, a searchable database, and a billing functionality. The interface may be adapted to receive from a client via a communications network a client data set containing information related to a functional magnetic resonance image. The processing engine may be programmed to identify a plurality of spatially independent components related to the client data set by applying a blind source separation algorithm to the client data set. The searchable database may include information related to (i) a plurality of sets of independent components corresponding to a plurality of functional magnetic resonance image data sets and (ii) a set of fundamental independent components comprising common components which exist in a scientifically-significant portion of the plurality of sets of independent components.
